commit: http://git.buildroot.net/buildroot/commit/?id=21d6e4ea459b0b3a436c7936a94a917f085919e6
branch: http://git.buildroot.net/buildroot/commit/?id=refs/heads/master

nsenter is a tool to enter the namespace of another process.

[Thomas: add dependency to 3.0 kernel headers, since the setns()
system call was added in Linux 3.0.]
